I am using

redirect\_to :back for my login form. It works perfectly.

However when I ran some tests I got errors.

No HTTP\_REFERER was set in the request to this action,so redirect\_to  
:back could not be called successfully. If this is a test, make sure to  
specify request.env[“HTTP\_REFERER”]

So I replaced all of my :back with request.env[“HTTP\_REFERER”] in my  
controller. Now I get another error

stack level too deep

What can I use that will work the same as :back but pass tests.

I tried request.env\_table[“REQUEST\_URI”] which passes the test but fails  
my application because it does not work the same way as :back

Thanks you for your time.

Mitch

I think what this means is that in the setup of your test you should  
set what the referer is (ie @request.env[“HTTP\_REFERER”] =  
"[http://something.example.com](http://something.example.com)  
" )
